About this document

Optimum Bitumen Content Test for OGFC by ANKIT SHARMA is a document available to read on EtoBox.

This document describes a test method for determining the optimum bitumen content (OBC) for open graded friction courses (OGFC). The test involves mixing aggregate samples with varying amounts of asphalt binder and measuring the amount of asphalt that drains from the samples after heating and loading. The OBC is the asphalt content that corresponds to 4 grams or less of drainage. The test is used to optimize mixtures containing unmodified or polymer/rubber modified asphalt binders.
